The Path of a Ronin (1080p;
53:44) is a nice exploration of the samurai-ninja aspect of the story,
including its roots in the actual Marvel comic books. There are the
requisite interviews with the principal cast and crew along with copious
clips from the film as well as some behind the scenes footage
(including a look at that supercool metallic bed that the elderly
Yashida lies on in the lab in his compound).
